Add Shingles Without Tearing Everything Off

Strom Roofing LLC performs roof layovers throughout Spokane when your existing roof consists of a single layer of shingles, the decking beneath shows no signs of rot or sagging, and you want to extend the roof's life without the cost and disruption of full tearoff. You consider a layover because the shingles have lost most of their granules and curled at the edges but the structure underneath remains solid, or because you need to improve weather resistance quickly and full replacement doeseds not fit your current budget. This approach installs new shingles directly over the old ones, reducing labor hours and disposal fees while giving you a fresh protective layer that handles rain and snow for another fifteen to twenty years if conditions allow.

Before recommending a layover, the crew inspects the existing roof to confirm that adding a second layer will not exceed the weight capacity of your framing and that no hidden moisture issues lurk beneath the surface. They check for soft spots by walking the roof and probing suspicious areas, look for dark stains on sheathing visible from the attic, and verify that flashing around chimneys and vents remains intact enough to integrate with the new shingles. If the evaluation reveals problems, they walk you through why a tearoff makes more sense and provide a separate estimate for that scope. When the roof passes inspection, crews install new drip edge if needed, apply starter strips along eaves, and begin laying shingles in staggered courses that cover the old material completely. Each row gets nailed through both the new and existing layers into the decking, securing everything as a unified system.

If you want to improve your roof's appearance and protection in Spokane without the expense of removing old shingles, requesting a layover evaluation helps you understand whether your roof qualifies and what limitations apply to this method.

What a Layover Changes and What It Does Not

You see a uniform color and texture across the entire roof with no trace of the worn shingles underneath, and the new surface sheds water without the rivulets that formed where old shingles had cupped. Strom Roofing LLC completes most layovers in one to two days since there is no tearoff phase, and the reduced timeline means less exposure to sudden weather changes that can soak open sheathing during a multi-day tearoff project. The added layer increases the roof's overall weight, so building codes in some jurisdictions limit layovers to one additional course, meaning if you already have two layers, a full tearoff becomes mandatory before any new shingles go on.

The new shingles bond to the slightly uneven surface of the old roof, which can create minor waviness visible in raking sunlight, though this does not affect performance. A layover does not include replacing underlayment or inspecting sheathing beyond what is visible from above and below, so any hidden rot or moisture damage remains unaddressed until a future tearoff. The method works best on roofs with minimal slope variation and no significant structural issues, and it extends roof life most effectively when paired with proper attic ventilation that limits heat buildup.

The estimate process clarifies which components get replaced, such as ridge caps and valley flashing, and which elements carry over from the original installation. If your roof has multiple layers already or if the crew finds decking concerns during the walkthrough, they explain why a layover is not advisable and outline the alternative approach with its associated costs and benefits.
